Remove empty elements from an array in Javascript

Question

How do I remove empty elements from an array in JavaScript?

Is there a straightforward way, or do I need to loop through it and remove them manually?

Answer 1

What about this(ES6) : To remove Falsy value from an array.

var arr = [0,1,2,"test","false",false,true,null,3,4,undefined,5,"end"];

arr.filter((v) => (!!(v)==true));

//output:

//[1, 2, "test", "false", true, 3, 4, 5, "end"]
